FAQs
Can I use red or white onions instead of sweet onions?
Yes, but sweet onions caramelize better and have a milder flavor.
Can I make these in an air fryer?
Yes! Air-fry at 375°F (190°C) for 7-9 minutes, checking for doneness.
Why did my crisps turn out soggy?
Make sure to:
- Slice onions thinly for better crisping.
- Let crisps cool before removing from the baking sheet.
- Use parchment paper to prevent excess moisture buildup.
Can I freeze these crisps?
No, freezing will cause them to lose their crispiness when thawed.
What’s the best dip to serve with these?
Try ranch, marinara, honey mustard, or garlic aioli for variety.
Can I make these dairy-free?
Use dairy-free shredded cheese for a lactose-free option.
Can I add protein to this recipe?
Yes! Sprinkle crumbled bacon or diced pepperoni on top before baking.
Do I need to flip the crisps while baking?
No, they crisp up evenly on their own.
How do I keep them crispy after baking?
Store them in a paper towel-lined container to absorb moisture.
